OK, let's work through this together. We're starting with 395 and we're going to multiply it by 33, which means we add 395 to itself 33 times.
Step 1: 0 + 395 = 395
Step 2: 395 + 395 = 790
Step 3: 790 + 395 = 1185
Step 4: 1185 + 395 = 1580
Step 5: 1580 + 395 = 1975
Step 6: 1975 + 395 = 2370
Step 7: 2370 + 395 = 2765
Step 8: 2765 + 395 = 3160
Step 9: 3160 + 395 = 3555
Step 10: 3555 + 395 = 3950
Step 11: 3950 + 395 = 4345
Step 12: 4345 + 395 = 4740
Step 13: 4740 + 395 = 5135
Step 14: 5135 + 395 = 5530
Step 15: 5530 + 395 = 5925
Step 16: 5925 + 395 = 6320
Step 17: 6320 + 395 = 6715
Step 18: 6715 + 395 = 7110
Step 19: 7110 + 395 = 7505
Step 20: 7505 + 395 = 7900
Step 21: 7900 + 395 = 8295
Step 22: 8295 + 395 = 8690
Step 23: 8690 + 395 = 9085
Step 24: 9085 + 395 = 9480
Step 25: 9480 + 395 = 9875
Step 26: 9875 + 395 = 10270
Step 27: 10270 + 395 = 10665
Step 28: 10665 + 395 = 11060
Step 29: 11060 + 395 = 11455
Step 30: 11455 + 395 = 11850
Step 31: 11850 + 395 = 12245
Step 32: 12245 + 395 = 12640
Step 33: 12640 + 395 = 13035

So, 395*33 = 13035
